Abstract: Energy internet is a distributed，open，diversified and emerging energy system，and its participants are of
diversity as well. In order to solve the problem affecting credible，safe and efficient energy trading among various
participants，blockchain technology is introduced into the trading on energy internet.Constructing a trading platform based
on hyperledger technology，and considering the needs of an energy internet project，the participants are divided into six
roles which are energy users，dispatching center，energy suppliers，trading settlement institutions，integrated energy service
providers and energy transmission service providers.The corresponding organizations for the roles are constructed，which
turn out to be a secure and decentralized energy trading system that can be audited by multiple participants and cannot be
tampered.
